Lung Cancer Screening Gaps Persist Despite New Guidelines: What You Need to Know

Lung Cancer Screening Rates Surge, But Gaps Persist: A Call for Equitable Access

Published March 21, 2025, by archyde.com

Miami, FL – As 2021, a pivotal year that saw the broadening of lung cancer screening guidelines to encompass younger individuals and those with a less extensive smoking history, the number of Americans undergoing these potentially life-saving procedures has undeniably increased. However, a stark reality remains: significant disparities in access persist, especially affecting those with limited access to healthcare.This unsettling finding comes from a recent study spearheaded by researchers at the Sylvester thorough Cancer Center, an integral part of the University of Miami Miller School of medicine. The study, published on March 20, 2025, in JAMA Oncology, sheds light on both the progress made and the considerable work that still lies ahead.

Lung cancer remains the leading cause of cancer deaths in the U.S., surpassing breast, prostate, and colorectal cancers combined. early detection through screening offers the best chance of successful treatment and survival. Low-dose computed tomography (LDCT) scans have emerged as a powerful tool in identifying lung cancer at its earliest, most treatable stages.

The Impact of Updated Guidelines: A Double-Edged Sword

The U.S. Preventive Services Task Force (USPSTF) initially published its lung cancer screening guidelines in 2013, recommending annual LDCT scans for individuals aged 55 to 80 with a smoking history of at least 30 pack-years. A pack-year is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years smoked – a metric that quantifies cumulative smoking exposure.

The 2021 update to these guidelines was a game-changer. Recognizing that lung cancer also affects younger individuals and those with less-heavy smoking histories, the USPSTF lowered the starting age for screening to 50 and reduced the pack-year requirement to 20. This expansion substantially broadened the pool of eligible individuals, theoretically increasing the number of lives that could be saved through early detection.

Tracy E. Crane, Ph.D., R.D.N., associate professor and co-leader of the Cancer Control Research Program at Sylvester, emphasized the impact of the revised guidelines, stating, “The updated guidelines substantially increased lung cancer screenings even as cancer screenings declined during the COVID-19 pandemic. Though, discrepancies for who is screened persist, underscoring the importance of addressing structural barriers in rural and underserved populations.”

Screening Rates: Progress and Persistent Disparities

The Sylvester Comprehensive Cancer Center study, lead by researchers like Rolle, revealed that before the guideline revision, only 15.43% of individuals deemed high-risk were current on their lung cancer screenings. following the 2021 update, this figure jumped to 47.08% – a considerable enhancement,but still falling short of reaching the majority of those at risk.

Even more concerning were the disparities observed across different populations. Screening rates were significantly lower among:

• Uninsured patients
• Individuals without a primary care provider
• Residents of rural areas

These findings underscore the critical need to address the systemic barriers that prevent equitable access to lung cancer screening.

Overall High-Risk Individuals	15.43%	47.08%
Uninsured Patients	*Data Unavailable*	*Significantly Lower*
Rural Residents	*Data Unavailable*	*Significantly Lower*

Barriers to Access: Unraveling the Challenges

Several factors contribute to the persistent gaps in lung cancer screening rates. These barriers can be broadly categorized as:

1. Lack of Awareness: Many eligible individuals, particularly those without a regular primary care physician, may simply be unaware of the updated screening guidelines and their own eligibility.
2. Referral Requirements: The need for a referral from a primary care provider can be a significant hurdle,especially for those lacking access to routine medical care.
3. Financial Constraints: While most health insurance plans cover lung cancer screening,the cost can still be a deterrent for uninsured or underinsured individuals. A single LDCT scan can cost hundreds of dollars,along with the expense of a doctor’s visit for the referral.
4. Geographic Limitations: In rural areas, screening facilities may be few and far between, requiring extensive travel. This poses a significant challenge for individuals with limited transportation options or mobility issues.
5. Mistrust and Fear: Some individuals may harbor mistrust of the medical system or harbor fears about the screening process itself, leading to reluctance to participate.

Rolle, a cancer survivor diagnosed at a young age, poignantly captures the patient’s viewpoint: “A person may say – I don’t have the money; I don’t have insurance.But, no one thinks they have cancer. I was diagnosed at 26. I understand how easy it is indeed to brush off a screening, especially among those choosing between having food or getting screened.”

Innovative Solutions: Bridging the Gap

recognizing the urgent need to address these disparities, healthcare providers, community organizations, and policymakers are actively working to implement innovative solutions.

• Mobile Screening units: Mobile lung cancer screening units are bringing essential services directly to underserved communities, including rural areas. These units, though costly (up to $2 million), eliminate transportation barriers and increase accessibility.
• Community outreach Programs: Institutions like the Sylvester Comprehensive Cancer Center are deploying community outreach teams to educate high-risk populations about lung cancer screening. “we have been identifying the places in our catchment area where the highest-risk patients are not getting screened. We then head over in the Game Changer Bus and educate and counsel the public on lung cancer screenings,” said study author Estelamari Rodriguez, M.D.,M.P.H., Sylvester’s associate director of community outreach for thoracic oncology.
• Patient Navigation Services: Patient navigators play a crucial role in guiding individuals through the screening process, from scheduling appointments and arranging transportation to providing emotional support and answering questions.
• Partnerships with Community Organizations: Collaborating with local churches, community centers, and health workers can definitely help build trust and deliver culturally sensitive education about lung cancer screening. According to study author Gilberto Lopes, M.D., Sylvester’s chief of the division of medical oncology, “Partnering with local community organizations, churches and health workers has proven effective in promoting lung cancer screening. Trusted local figures can help overcome mistrust and fear while providing culturally tailored education.”
• Financial Assistance Programs: Many states and non-profit organizations offer programs to help offset the cost of lung cancer screening for uninsured or underinsured individuals.

The Road Ahead: A Call to Action

The progress made in expanding lung cancer screening eligibility and increasing screening rates is commendable. However, the persistent disparities in access highlight the urgent need for concerted efforts to ensure that all Americans, irrespective of their socioeconomic status or geographic location, have the opportunity to benefit from early detection.

“I was lucky enough to catch my breast cancer early,and now I’m cancer-free.I woudl love for others to get screened so they can also catch cancer early, too,” said Rolle, underscoring the personal impact of early detection.

this requires a multi-pronged approach involving healthcare providers, policymakers, community organizations, and individuals themselves. By raising awareness, addressing systemic barriers, and promoting equitable access to screening, we can save lives and reduce the burden of lung cancer in the united States.

Screening Rates and disparities

Archyde News Editor: Dr. Hayes, the recent data indicates that lung cancer screening rates have increased since the guideline updates in 2021. However, considerable disparities persist. Can you elaborate?

Dr. Hayes:

Certainly. While we’ve seen a positive trend, with screening rates jumping from under 16% to nearly 50% among high-risk individuals after the 2021 guideline revisions, we must acknowledge the gaps. Specifically, uninsured individuals, residents of rural areas, and those without a primary care provider are significantly less likely to be screened. This is a major concern.

Barriers to Access

Archyde News Editor: What do you see as the primary barriers preventing equitable access to lung cancer screening?

Dr. Hayes:

The barriers are multifaceted. Lack of awareness is a meaningful issue, as many eligible individuals, especially those without regular medical care, may not know about the updated guidelines. Referral requirements,financial constraints,geographic limitations,and mistrust of the healthcare system form a complex web that prevents many from accessing life-saving screenings. For those with financial challenges, even with insurance, the additional costs for the procedure and doctor’s visit can be a significant obstacle. Transportation issues and limited screening facilities in rural regions, along with potential fears surrounding medical procedures also prevent individuals from getting screened.

Innovative Solutions

Archyde News Editor: What innovative solutions are being implemented to address these barriers?

Dr. Hayes:

We’re seeing some promising initiatives. Mobile screening units are bringing services directly to underserved communities. Community outreach programs are also crucial for educating high-risk populations. Patient navigation services are helping guide individuals through the screening process, and partnerships with local organizations are crucial for building trust and delivering culturally sensitive information. Additionally, financial assistance programs are helping to offset costs for those in need. These combined efforts will play a role in addressing rising costs and improving screening rates.

A Call to Action

Archyde News Editor: What’s your call to action for healthcare providers, policymakers, and the community?

Dr. Hayes:

We need a multi-pronged approach. Healthcare providers must actively promote screening,address patient concerns,and remove referral barriers wherever possible. Policymakers should expand access to affordable healthcare, support expanded screening programs, and invest in infrastructure. Community organizations can play a critical role in outreach and education.And individuals need to be proactive with their health and discuss screening eligibility with their doctors. Every single effort matters, because we’re talking about saving lives.
